I think the issue lies in the fact that data science is a massive umbrella term which really covers multiple large fields, namely statistics and computer science, both of which by themselves are massive. Its very difficult if not impossible for people to feel like they have enough expertise in all of the subjects that fall under the umbrella of "data science". Which typically leads to lots of self-teaching, learning on the fly, and hacking solutions together, which is often the source of all impostor syndrome feelings.
